An expression. it´s used when a person is really pissed off for any reason. It could also be used if something hurts. If a guy gets rammed really hard with a huge cock in his tight anus and it hurts,. he will say it,. or if after waiting 30 min in the line for entering a club, the guards don´t let you in,. then you say it.
